Synthetic-user startup Simile raises $200M at $2B valuation 5 months after $100M Series A

Simile raised a $200 million Series B led by Greenoaks at a $2 billion valuation.

The startup builds synthetic users for marketing and product research and counts CVS Health as a customer.

The deal came just five months after its $100 million Series A led by Index Ventures.

The rapid funding shows strong investor appetite for AI tools that simulate human feedback, despite questions about their accuracy.
